I've been getting CRS from Fishy Business in Columbia and have been pleased with what I've received. They are all in my 55 gallon tank. My shrimp have bred at least twice in the last few months, with nice looking offspring. I am looking for a different source of shrimp to add to my tank, in hopes of mine not becoming too inbred. Does anyone know where I might get some? any thoughts on if this is a good idea or if I am just getting concerned over nothing? I've never kept shrimp before so any input would be greatly appreciated. Thanks!
